This invention relates to improvements in liquid dispensing apparatus,such for example as that commonly used for dispensing measuredquantities of gasoline, oil, and the like.

More particularly, the invention relates to a species of protectivemechanism designed to prevent delivery of liquid to the customer unlessand until the register, which indicates the quantities of liquiddispensed, has been reset to zero.

The object of this invention is to accomplish the above broad purpose ina manner which will enable operation of the pump, or other means used toforce the gasoline through the meter, and yet make it certain that nogasoline can be delivered to the tank of the customers car until theregister has been reset.

It frequently happens that the visible dischargeindicator is notcompletely filled, as it should be, at the start of a dispensingoperation. For various reasons, the level of liquid in such indicatormay drop, particularly if considerable time elapses between dispensingoperations. With apparatus of the now-prevalent form, the pump cannot bestarted until the register has been reset to zero. Then, if the visibledischarge indicator needs replenishment, the quantity pumped for thispurpose will be shown on the register and, being usually a smallquantity, the customer may not notice it and the operator may not botherto reset the register to zero before starting delivery to the customer.The result will be that the customer will get less than is indicated onthe register and less than he pays for. It is better then to allowoperation of the pump, previous to resetting the register, for thepurpose of replenishing the visible discharge indicator and then, afterthe latter is properly filled, to reset the register and clear it of thequantity indicated thereon, which quantity is the sum of the quantityused for replenishing the visible discharge indicator and the quantitydispensed on the previous sale.

This invention has for an object to provide means for locking the hosenozzle to its support so that it cannot be removed and placed in thetank of a customers car unless and until the register has first beenreset to zero and at the same time to allow the flow-control means to beoperated (preferably only when the operator is near the pump and in amanner requiring his constant attention) while the nozzle is locked upon its support.

Other objects and advantages will appear as the detailed descriptionproceeds and will be pointed out in the appended claims.

The invention will be disclosed with reference to the accompanyingdrawings, in which:

Fig. 14 is a fragmentary view illustrative of a third form of switchoperating lever.

Referring to these drawings and. particularly to Fig. 1 thereof, theapparatus includes a suitable pump l5, driven by an electric motor I6 bythe belt 11. This pump draws gasoline up through a suction pipe I1 froman underground supply tank (not shown) and forces such gasoline upwardlythrough a pipe l8 to a suitable meter IS. A discharge pipe 20 leadsupwardly to a suitable elevation and has connected thereto one end of aflexible hose 2|. Usually a visible discharge indicator, such as 22, isinterposed between the pipe 20 and hose 2|. The other end of the hosecarries a nozzle 23 of the usual type having within it a self-closingvalve which has a stem 24 extending out of the nozzle casing foroperation by a hand lever 25. As shown, the nozzle valve is closed, butwhen lever 25 is moved toward the nozzle casing the valve will beopened. A guard 26, fixed to the nozzle casing, is provided for lever25. The meter I9 drives through a shaft 21 a suitable register 28 forindicating the measured quantities dispensed. In this case, the register28 is of the computing type and has a set of dial wheels 29 forindicating the quantity dispensed and another set of dial wheels 30 forindicating the cost of such quantity. The register includes suitablemeans for resetting the dial wheels to zero and such means are operableby turning a shaft 3l,a hand crank 32 being provided for this purpose.The motor [5 is provided with a suitable switch contained in a casing33. The apparatus thus described is enclosed except for the hose 2|,indicator 22, nozzle 23, and reset crank 32, by a casing 34, from whichall the elements described are suitably supported. The casing of coursehas suitable openings to allow the dial wheels 29 and 30 to be seen.

The apparatus, thus far described, is old and well known in the art anda more detailed description and illustration of it is unnecessary to anunderstanding of the present invention. Also, such apparatus may vary inform and arrangement,--the only requisites being a meter, a registerdriven. by the meter and having resetting means, some means for forcingliquid through the meter and to the hose, a nozzle for the hose and asupport therefor, together with some means for controlling the flow ofliquid, usually but not necessarily in all cases, an electric switch forstarting and stopping the pump motor.

In the first form of the invention, the switch is operated from outsidethe casing 34 by a lever 35 fixed to the outer end of a shaft 36. Thisshaft is rotatably mounted in a bracket 31, fixed as indicated in Fig. 2to a cross bar 3'5, which forms part of the frame of the housing 34. Thebracket El forms a support for the nozzle 23, the lower and horizontalportion of guard 26 resting on said support. Such portion is slotted(Figs. 2 and 5) to receive an upstanding lug on support 31 and the lugis perforated to receive a padlock whereby the nozzle may be locked inits illustrated and inactive position, independently of the other nozzlelocking means later to be described. The switch lever 35 has a lug 39which, when the lever is turned in a counterclockwise direction from theposition marked A (Fig. 2) to that marked B, will abut the guard 25 ofthe hose nozzle and prevent the switch lever from being moved to thefull limit of its range of movement in this direction,such limit beingindicated as position C. A lug ill (Fig. l) on the lever 35 prevents itfrom being moved in a clockwise direction beyond the position A shown inFig. 2. The inner end of shaft 35 has fixed thereon an arm ll which isconnected by a link 42 (bearing a weight 53) to an arm i fixed on theshaft 45 of the switch. When the parts occupy the positions shown inFig. 2, the motor switch is open. The lever 35 may, however, be movedwhile the nozzle is on support 3'! to position B, which is far enough toclose the motor switch. Whenthe lever 35 has been turned into position Bthe motor and pump will be operated but the lever must be manually heldin this position. If the operator releases lever 35, the weight "5'3will move the parts to position A and automatically open the motorswitch. When the nozzle 23 is removed from its support, lever 35 may bemoved into the position C. The parts then occupy the positions shown inFig. 3, and the axis of the pivotal connection between link 42 and lever4i lies to the left of a vertical plane passing through the axis ofshaft 36. Hence,

the weight 43 will then tend to move the lever in a counterclockwisedirection but such movement is limited by a stop :56 fixed to thebracket 3?. Thus, the switch will be held in closed position so that thepump motor may be continued. in operation without manual attention bythe operator. To enable the additional movement of lever 35 in acounterclockwise direction after the switch has been closed the link i2is made in two relatively movable sections,-the lower forked end 22being slidable on the other portion. A spring ll coiled on the lower endof link 62 acts between a collar '23 fixed on such end, and the upperend of fork 3-2 to hold the parts in the positions illustrated, whereina nut on the link abuts fork 42. However, the spring will yield to allowlink 42 to be drawn up after the switch is closed. When the nozzle 23 isreplaced on its support, the lever 35 has to be moved in a clockwisedirection, out of interfering relation therewith and, when moved thusfar, the weight will come into play to move the lever back into theposition shown in Fig. 2 in which the switch is open.

This invention provides a means for locking the nozzle on its supportunless and until the register 23 has been reset to zero. Such means arecontained for the most part in a casting 8 which is suitably secured toa cross bar 51 (Fig. 1) forming part of the frame of housing 34. Theupper part of this casting has two spaced cars 52 which rotatablyreceive one end of the resetting shaft 35. Casting Eiil (Figs. 5 and 6)has a chamber in one face opening adjacent a side wall of casing 8 3.Mounted to turn in this casting and extending horizontally across thechamber is a shaft 5d. Fixed to this shaft, near one end, is a finger 55which extends through a slot in in the casing 3 and is adapted to entera hole 56 in the vertical part of the guard 28 of the hose nozzle. Fixedto shaft 54, near the other end, is an arm fill, the outer free end ofwhich is slotted to receive a pivot pin 58, fixed in the lower end of afork 59. The fork is fixed to a rod 69, vertically slidable in thecasting and extending above its upper end into the space between theears 52 and in. position to engage a disk ii i, fixed to the reset shaft3 i. This disk has a single notch 62 in its periphery and the notch islarge enough to receive the upper end of rod 60. The reset shaft Si isintended to be turned one complete revolution in order to reset theregister 28. At the start and at the end of this resetting operation,the disk ii is positioned as in Fig. 6 so that rod 66 can freely enternotch 52 and thus allow shaft to turn, provided its lock, to'bedescribed, has been released. However, should one start to reset theregister and not turn shaft Ell the intended complete revolution., thendisk El will be turned to some intermediate position in which notch 62will be out of line with rod Gil. Then the rod Ell, if lifted, will abutthe periphery of disc GI and prevent movement of shaft 5 5 and finger toa degree sufiicient to enable removal of the nozzle from its support.While rod 6?! is always free to rise a certain amount and thus enablesthe nozzle 23 to be lifted vertically, it cannot be lifted far enough toenable the removal of nozzle 23, for which purpose the guard must belifted above lug 38.

The normal locking device for the hose nozzle includes a cam 63, fixedto shaft i l and having a shoulder 64 which is adapted, as shown in Fig.7, to abut one end 01' a locking bar 65, if

the finger 55 is lifted to any great extent. Particularly, the finger islocked against vertical movement to an extent sufiicient to allowremoval of nozzle 23 from its support. The bar 65 is pivotedintermediate its ends on a stud 66 fixed to casting 50 and a spring 6!tends to force the right-hand end of the bar downwardly against theperipheral part of cam 63 which lies back of shoulder 64 (to the left asviewed in Fig. 7). The left-hand end of bar 65 supports the lower end ofa vertical rod 68, slidably mounted in casting 50 and having its upperend disposed in the path of a cam 69 fixed on shaft 3|. Thus, thelocking bar may be released by turning reset shaft 3|, by means of crank32, through one revolution, which will cause cam 69 to depress rod 68and force the right-hand end of bar 65 upwardly out of the path ofshoulder 6-3 or into the position shown in Fig. 9.

When the locking bar 65 has been lifted, as just described, it is heldwith its right-hand end elevated above cam 63 by a segment 10 in themanner shown in Figs. 9 and 10. This segment is mounted to turn freelyon shaft 54 and is held against axial displacement on the shaft betweenthe hub of cam 63 and a washer 1|, which in turn is held in place by apin 12. A spring 13 tends to turn segment I in a clockwise direction asviewed in Figs. '7 and 10. Hence, when the right-hand end of bar 65 israised, as above described, the segment'will be moved by spring 13 fromthe position shown in Fig. 7 to that shown in Fig. 1.0, wherein thesegment 10 abuts a lug M on cam 63 and thus its clockwise movement isarrested. Clockwise movement of cam 63 is prevented by the abutment offinger 55 with the bottom the slot 15 in the casing 34 (Fig. 5.)

When the finger 55 has been unlocked, it is free to swing in acounter-clockwise direction, and the nozzle 23 can be lifted verticallyto a position wherein the horizontal portion of the guard 36 clears thetop of lug 38, after which the nozzle is svwing outwardly from casing 34to withdraw the vertical portion of the guard 26 from finger 55. As thefinger 55 is moved upwardly by the removal of the nozzle from itssupport, it turns cam 63 and the lug I4 thereon moves segment 10backwardly out of supporting relation with the bar 65. The peripheralsupporting surface of segment 16 is of slightly greater radius than theperipheral surface of cam '53. Consequently, as the segment 10 is moved.from in under bar 65, the latter drops slightly, as will be clear fromFig. 13, so that if one then attempts to move finger 55 or cam 63clockwise, the segment will be held from moving clockwise with the cam.Then, as the cam 63 is thus moved, the bar 65 is forced into theposition shown in Fig. '7, thus locking the finger 55 until the resetshaft 3| is again operated.

The right hand end of bar 65 slides over an abutment 16 formed oncasting 50, which prevents deflection of the bar by pressure of the camon it if one'attempts to force finger 55 upwardly when it is locked.

The operation will be briefly summarized. Normally, the hose nozzle 23rests upon its support; the switch lever 35 is held in off position bythe weight 43; and usually the register 28 is no reset and the dials 29and 30 are left showing the result of the previous dispensing operation.Assuming these conditions, the parts are positioned as shown in Figs. 1,2, 5, 6 and '7. The notch 62 of disc 6! will be positioned to receiverod 60, as shown in Fig. 6. The finger 55 register 28 in the usual way.

will be locked by the bar 65 engaging in back of shoulder 64 of earn 53as shown in Fig. '7. The nozzle 23 will thus be locked to its support.Lever 35 can be moved counterclockwise from the position A to position Bshown in Fig. 2 far enough to turn on the switch of the pump motor andthe latter can then be operated but the operator must manually hold theswitch lever raised. If he releases it, the weight 43 will automaticallymove the switch to open position. To maintain the switch closed, withoutmanual effort, lever 35 must be moved to the position C and this ispossible only after nozzle 23 is removed from its support. Before thiscan be done, the nozzle must be unlocked and an operation of the resetshaft 3| is necessary for this purpose, whereby resetting of theregister is insured. It is necessary to turn the reset shaft 3| one fullrevolution from the position shown in 6 in order to restore the dials ofthe register 28 to zero position and clear the register. When the shaft3| is thus turned, the notch 62 will again be positioned for entrance ofrod 60. But if shaft 3! is turned less than one revolution, the rod willprevent removal of nozzle 23. It will abut disc El and thus preventturning of shaft 54 to an extent sufficient to release the nozzle Theoperation of shaft 3| will cause cam 69 to raise bar 65 into theposition shown in Figs. if) in which i is held by segment Ill. Thelcckine finger 55 is now free to swing upwardly the nozzle 23 may belifted far enough to be removed. The removal of the nozzle turns finger55 and shaft 54, liftrod 6!! into the notch. 32 and locking theresetting shaft operation. Also, the earn 3 will move back the segmentinto the position shown in Fig. in readiness for a succeeding operation.With the nozzle 23 removed from its support, lever 35 may now be turnedto the positi C in which the weight 43 will act, as shown in Fig. tohold the motor switch in closed pos tion. T usual dispensing operationnew ensues. the quantity and cost of the liquid dispensed being shown bythe dials 29 and 30 of When the dispensing operation has been completedthe operator replaces the nozzle on its support but, before he can dothis, le er 35 must be moved in a clockwise direction to such an extentthat weight 43 will move the motor switch to the off position A shown inFig. 2. The nozzle can then be replaced on its support by firstinserting its discharge end in the socket T! (Fig. 1) provided in thepump casing and swinging it, while held slightly elevated above support31 into the position shown Fig. 11, allowing the then raised lockingfinger 55 to enter the hole 56 in the guard 26 of the nozzle. Then, withthe parts positioned as in Fig. 11, the nozzle is lowered until it restson its support 31. As the nozzle is lowered, the upper wall of hole 55will engage the finger 55 and swing it downwardly. The parts are nowpositioned as in Fig. The finger 55 has been depressed and 63 been movedback into the position shown in Fig. '7 so that the locking bar 55 hasbeen moved back into locking position. The nozzle thus becomesautomatically locked to its support and cannot be released until shaft3! has again been turned one complete revolution, causing the registerto be fully reset.

A modification of the invention is shown in Fig. 4. Here exactly thesame nozzle locking means are used as have been above described.

The essential difference is that switch lever 35', which is shown in offposition, cannot be moved in a counterclockwise direction to on positionbecause of the abutment of a lug 39' with the guard 26 of nozzle 23.Removal of the nozzle from support 31 will, of course, permit lever 35to be turned to on position. Or, and as herein illustrated, the nozzle23 may be lifted vertically far enough to permit lug 39' to pass beneaththe lower portion of the nozzle guard and yet not far enough to enablesuch portion to clear the top of the lug 38', which has been madesomewhat higher than lug 38 for this reason. Freedom for the necessarylimited vertical movement of nozzle 23 may be had by the lost motionprovided in the locking device (between shoulder 64 and bar 65) and/orthat provided by the hole 56 in the guard 26 of nozzle 23. In thismodification, the weight 43 is omitted and the switch lever 35' ismanually moved in both directions.

Another modification is shown in Fig. 14. Here again, the samenozzle-locking means are used. Also a fixed support secured to bar 5|,is used for the nozzle 23,the support having an upstanding lug 8|, highenough to allow the nozzle 23 to be lifted to a limited extent, as itwas in the form shown in Fig. 4 without releasing the nozzle-lockingmeans and without completely disengaging the guard 26 from the lug 8i.Alongside the hose support 8!) is a switch operating lever 82, pivotedintermediate its ends at 83 to support 80 and having its rear endconnected by a link 84 to the lever 44 of the motor switch. The outerend of lever 82 is engaged by the guard 26 of nozzle 23. When the nozzle23 is placed on support 80, its weight moves lever 82 to the illustratedposition in which the switch is opened. The arrangement here is suchthat the nozzle 23 may be lifted far enough, Without unlocking it andwithout releasing it from lug 8|, to en able lever 82 to be moved,manually or otherwise, upwardly far enough to close the motor switch.Here again, the operator has to manually maintain the switch in closedposition by holding the weight of the nozzle off the lever. The momenthe releases the nozzle, its weight bears on lever 82 and moves it toopen the switch.

In all three forms of the invention the nozzle is locked against removalfrom its support by means which are releasable only after the registerhas been reset to zero. And in all three forms of the inventionoperation of the pump is possible before the register has been reset tozero. It is possible also to force gasoline through the meter in the notinfrequent cases when the visible discharge indicator 22 is notcompletely filled, and in fact the necessity of replenishing suchindicator is one of the reasons for the development of this invention.Obviously, the indicator 22 if it needs filling should be filled priorto the resetting of the register. To fill it afterward, as hasheretofore been done, results in the registration of the quantity usedfor replenishment on the dials of the register. The quantity shown onthe register will be greater than that secured by the customer and thecustomer will have been cheated. With this invention, the pump may beoperated enough to replenish the indicator 22 and the resetting of theregister effected afterward. The fact that the motor and pump may beoperated before the register has been reset leads to no fraud on thecustomer because the nozzle 23 is locked to its support and cannot beinserted in the tank of the customers car. And

before the nozzle can be unlocked and removed, the register must bereset to zero. The arrangement is thus a better one than that which hasheretofore been proposed and which is characterized by the prevention ofoperation of the 4 pump and motor unless and until the register has beenreset to zero.

It is possible also to force gasoline out of the nozzle 23 previous toresetting of the register. The valve lever 25 may be, and often is,slotted, as shown at 86 in Fig. 5, so that it can clear the lug 38,thusenabling the lever to be moved to open the nozzle valve while the nozzleis in place on its support. Thus, by pressing lever 25 toward the nozzlebody and at the same time operating the switch lever 35, gasoline can beforced out of the nozzle. Naturally, this is a useless operation but,even if such a foolish operation is performed, the service station ownerand not the customer will be cheated. The nozzle still remains locked toits support and unless and until it is removed, the customer well knowsthat he isnt getting any gasoline even though he observes the dials ofthe register moving and sees the flow of gasoline in the indicator 22.And the removal of the nozzle compels as a prerequisite the resetting ofthe register to zero.

The invention thus affords a better and more effective means forinsuring a cleared register just prior to a dispensing operation and forprotecting the customer against dishonest service station attendants whoattempt to cheat the customer by fraudulent manipulation of theapparatus.
